We know Hayden Panettiere best from her role as a teenage cheerleader on the TV series “Heroes,” but now she has a movie to promote, so she showed her grown up side in this sexy photo shoot Michael Sterling Eaton.

The n0w 21-year-old Hayden told E! News about her role in “Scream 4”: “I can’t tell you if I live, die, am the killer or not the killer. You get a lot of scripts for horror movies and as we know horror movies either can be amazing or there can be really horrible so I was always nervous about doing one. But then this came along and with the cast that was involved and Wes Craven directing it? It seemed like such a blast.” If it’s anything like the first three, “Scream 4” will be big hit!
